Windows has command line utilities that show us the version of the Windows OS running on the computer, including the service pack number. There are multiple CMD commands that help with finding this, you can pick the one that suits your need. Ver command can show you the OS version whereas Systeminfo command can additionally show service pack number, OS edition and build number etc.
Find Windows Version from CMD
systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
C:\>systeminfo | findstr /B /C:"OS Name" /C:"OS Version" OS Name: Microsoft Windows 7 Ultimate OS Version: 6.1.7600 N/A Build 7600
In case of Windows 7 SP1, the output would be slightly different as below.
c:\>systeminfo | findstr /B /C:"OS Name" /C:"OS Version" OS Name: Microsoft Windows 7 Enterprise OS Version: 6.1.7601 Service Pack 1 Build 7601
If you want to print more details, then you can use just ‘OS’ in the findstr search pattern. See example below for Server 2008.
